【摘要】：目的:观察经临时冠牙龈成型后的上前牙种植修复负重1年后的牙龈形态学变化,探讨临时冠对牙龈组织进行干预的可靠性。方法:选择北京大学口腔医院第二门诊部2010年3月至2011年11月间因上前牙缺失要求种植修复的患者78例(男37例,女41例),在行种植上部修复前采用种植体支持的临时冠进行牙龈形态的诱导,直至永久修复完成。在修复即刻及1年后测量近、远中牙龈乳头及唇侧龈缘水平高度的变化。结果:所有病例在经过牙龈成型后再进行种植上部修复,修复1年后近、远中牙龈乳头高度变化分别为(0.16±0.58)mm和(0.10±0.53)mm,唇侧牙龈水平变化仅为(0.10±0.41)mm。经临时冠诱导成型后的牙龈形态在种植修复1年前后的变化差异无统计学意义(P0.05)。结论:严格掌握适应证,采用种植体支持的临时冠在前牙美学区的种植修复中对软组织的成型技术临床可行,近期美学效果可靠。
[Abstract]:Objective: to observe the changes of gingival morphology after implant restoration with temporary crown for 1 year, and to explore the reliability of temporary crown intervention on gingival tissue.Methods: from March 2010 to November 2011, 78 patients (37 males) were selected from the second outpatient Department of Peking University Stomatology Hospital.In 41 cases of female, gingival morphology was induced by implant supported temporary crown before the upper implant restoration was carried out, until permanent restoration was completed.The changes of the level of proximal and distal gingival papilla and labial gingival margin were measured immediately and 1 year after repair.Results: after gingival formation, all the patients were repaired with the upper implant. The height of the proximal and distal gingival papilla was 0.16 卤0.58)mm and 0.10 卤0.53 mm, respectively, and the level of the labial gingival was only 0.10 卤0.41 mm..There was no significant difference in gingival morphology after temporary crown induction before and after 1 year of implant repair.Conclusion: the indication is strictly grasped and the temporary crown supported by implants is feasible for the soft tissue reconstruction in the aesthetic area of anterior teeth and the short-term aesthetic effect is reliable.
